DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The present invention will be further described below with reference to specific preferred embodiments, but the scope of protection of the present invention is not limited thereby.

[0031] For the convenience of description, the relative positional relationships of components, such as upper, lower, left, and right, are described according to the layout directions of the drawings in the specification, and do not limit the structure of this patent application.

Embodiment 1

[0032] As shown in FIGS. 1-6, an atomizer of this embodiment includes an e-liquid storage assembly 1, an e-liquid guide assembly 2 arranged at the bottom of the e-liquid storage assembly 1, and an atomization assembly 3 clamped with the e-liquid storage assembly 1.

[0033] The e-liquid storage assembly 1 includes a housing 11 and a plug 12 connected to each other, and the housing 11 and the plug 12 are connected to form a structure with an e-liquid bin 13 formed inside. The plug 12 is preferably an elastic silica gel plug.

[0034] The middle part of the plug 12 is provided with a mounting groove 121, the top of the mounting groove 121 is provided with anabutting portion 122 protruding toward the mounting groove 121, and a first-level mounting step 123 and a second-level mounting step 124 are sequentially provided in the mounting groove 121 from top to bottom.

[0035] The e-liquid guide assembly 2 includes an e-liquid guide ceramic 21 arranged at an upper part of the e-liquid guide assembly 2, e-liquid guide cotton 22 arranged at a lower part of the e-liquid guide assembly 2, and a spring 23 between the e-liquid guide ceramic 21 and the e-liquid guide cotton 22.

[0036] The e-liquid guide ceramic 21 is a solid ceramic, and the solid ceramic is formed with micropores for conducting e-liquid.

[0037] The e-liquid guide ceramic 21 includes a ceramic body 211 in direct contact with e-liquid in the e-liquid bin 13, and two e-liquid guide legs 212 arranged at the bottom of the ceramic body 211; two ends of the ceramic body 211 are placed on the first-level mounting step 123 in the mounting groove 121, and the two e-liquid guide legs 212 are placed on the second-level mounting step 124.

[0038] Two ends of the e-liquid guide cotton 22 are abutted against the second-level mounting step 124 in the mounting groove 121 by the two e-liquid guide legs 212 of the e-liquid guide ceramic 21, and the two ends of the e-liquid guide cotton 22 cover the e-liquid guide leas 212.

[0039] The ceramic body 211 and the e-liquid guide leas 212 of the e-liquid guide ceramic 21 are integrally sintered from the same material. The ceramic body 211 is in direct contact with the e-liquid in the e-liquid bin 13, and absorbs and conducts the e-liquid to the e-liquid guide legs 212 and the e-liquid guide cotton 22. Because the porosity of the sintered e-liquid guide ceramic 21 is stable (the porosity is determined after the e-liquid guide ceramic 21 is sintered), no matter whether the temperature of the e-liquid is normal temperature or high temperature (the temperature when the e-liquid is not atomized) and no matter whether the viscosity of the e-liquid decreases or not, the amount of e-liquid passing through the e-liquid guide ceramic 21 per unit time is constant, and the e-liquid guide rate of the e-liquid guide ceramic 21 is stable. Therefore, the amount of e-liquid absorbed by and conducted on the e-liquid guide cotton 22 is stable, which can avoid the phenomenon that the atomization piece 322, which is in contact with the e-liquid guide cotton 22, is dry-burnt due to little e-liquid or immersed in excessive e-liquid.

[0040] In order to prevent the e-liquid guide ceramic 21 from falling out after assembly, the e-liquid guide ceramic 21 is abutted by the abutting portion 122 on the plug 12.

[0041] The atomization assembly 3 includes a base 31 which is hollow and an atomization head 32 arranged in the inner cavity of the base 31.

[0042] The atomization head 32 includes an atomization sleeve 321 which is conductive and hollow. An atomization piece 322, an insulating seat 323, and an electrode assembly 324 are sequentially arranged in the inner cavity of the atomization sleeve 321 from top to bottom. The electrode assembly 324 has a positive terminal 3241 and a negative terminal 3242 isolated from each other.

[0043] The upper end of the atomization sleeve 321 is abutted to an upper surface electrode of the atomization piece 322, the lower end of the atomization sleeve 321 is electrically connected to the negative terminal 3242 of the electrode assembly 324, and a lower surface electrode of the atomization piece 322 is electrically connected to the positive terminal 3241 of the electrode assembly 324.

[0044] The atomization piece 322 is in contact with the bottom of the e-liquid guide cotton 22, an atomization cavity 4 is formed between the atomization piece 322 and the e-liquid guide ceramic 21, an air outlet channel 14 connecting the atomization cavity 4 with outside air is formed in the e-liquid storage assembly 1, and an air inlet channel 33 connecting outside air with the atomization cavity 4 is formed in the atomization assembly 3 and at the lower part of the e-liquid storage assembly 1.

[0045] When this embodiment is used, a user inhales from the outer end of the air outlet channel 14 of the e-liquid storage assembly 1, outside air enters the atomization cavity 4 from the air inlet channel 33, e-liquid is guided from the e-liquid bin 13 to the atomization piece 322 via the e-liquid guide assembly 2, the atomization piece 322 is electrically connected to an external power supply via the atomization sleeve 321 and the electrode assembly 324 to implement ultrasonic atomization, and smoke after the ultrasonic atomization flows to the user's mouth via the air outlet channel 14 and is inhaled by the user.

Although the present application is disclosed above with the preferred embodiments, the present application is not limited thereto.
